Wrong Gong Rung (Treasure Mode)

Head left from the starting point and you'll find a large group of civilians wandering around for no particular purpose. There's a sparkling pile of rocks nearby, so switch to the British Commander if you're not already controlling him. Blast the rocks apart and you'll reveal some pieces. These can be assembled to form a device that will ring a loud gong. To make that happen, have Indy latch onto the switch on the right side of the booth and give it a pull. The gong will sound and you'll see a short sequence.

(Above Left) A funny thing happened on the way to the market... (Above Right) Construct and repair the water wheel along the area's left side to produce a stream of LEGO pieces.

Following the sequence, you'll find yourself facing ten enemies with swords. The crowds that were milling about previously are now running in circles in a panicked state. Continue ignoring them as you deal with the dangerous swordsmen. You can steal a sword from one of the first ones you defeat, then use it to easily cleave any goons that follow.

When the last of the goons are defeated, the area treasure chest will appear atop a tree. However, you can't possibly reach it just yet. To do that, you'll need to use the elephant, but don't go there just yet or you'll miss out on some easy LEGO pieces. Instead, head toward the far left of the area. There, you can destroy a cannister with a bazooka blast and use the scraps to initiate repairs on the nearby water wheel. Demolish any remaining debris in the area, as well. When you finish, you should see two gears that you can carry around and place on the left side of the wheel. Once those are in position, you can hop onto the strip in front of the wheel and run toward it to cause the wheel to spew small LEGO pieces.

Once you're ready to finish the area, head up to the cage where the elephant is waiting. Blast down its gate with the British Commadner's bazooka, then hop on board the animal and walk it over to the tree. Jump from its back to the branches of the tree to collect your reward and finish the stage.
